Black Friday video game deals?
I picked up the PS4 Battlefield 1 Revolution bundle for $30 (full game plus four DLC packs). For shooters, Wolfenstein II was also on sale for $30 (half off) or the digital deluxe edition for $40.

Rising Storm 2: Vietnam is $12.49 on Steam
Note: developers are still adding new content, a new Australian faction is being added soon. (new weapons, new commander strikes, new helicopter as well)

Cities: Skyline is $7.50 on Steam
Doom (2016) $15
Sunless Sea $6.26
